A prospective double-blind, placebo-controlled, randomized study of 24 weeks duration was carried out comparing the efficacy and tolerability of sulphasalazine (SSZ) versus placebo in patients with psoriatic arthritis. A total of 120 patients were included in nine centres. All patients had active disease and fulfilled the criteria of definite psoriatic arthritis of at least 3 months duration. They received either SSZ (2.0 g/day) or placebo. Efficacy variables included pain, patient's overall assessment of joint and skin improvement, morning stiffness, Ritchie articular index, ESR and CRP. An intention-to-treat (TTT) analysis was performed for the 117 patients who qualified (three patients did not qualify due to missing data after baseline). A per-protocol analysis was performed for the 81 patients who completed the 6 months study period (SSZ = 38, placebo = 43). Major reasons for withdrawal were inadequate response (SSZ = 4, placebo = 7) and adverse events (SSZ = 8, placebo = 12). Pain was the only statistically significantly different primary outcome variable at end point in favour of SSZ in the ill analysis. No significant differences were present in other clinical or biological variables, although there was a trend in favour of SSZ for some variables. SSZ, at a dose of 2.0 g/day, appeared to be a safe treatment in patients with psoriatic arthritis. At this dosage, its efficacy was only demonstrated for the pain variable. [ABSTRACT FROM PUBLISHER]

Introduction. – Multiradicular nerve root compression, and long lasting radicular syndrome occur very often. They happen particularly on degenerative spine. Huge synovial cyst of the zygapophyseal joints may account for it, expand in the epidural area and cause radicular syndrome.Exegesis. – Two cases of huge synovial cysts spreading into the spinal channel are reported here. Diagnostic and therapeutic modalities are discussed. On degenerative spine, facet joints osteoarthritis may result in synovial cysts. Physical examination findings are radicular syndrome.Conclusion. – Huge synovial cysts may result in multiple nerve root compression syndrome, as reported in our two cases. Typically, there''s no history of preceding trauma and symptoms appear progressively. Magnetic resonance imaging of the spine shows an intra-spinal round mass with typical signal intensity and capsular formation. Treatment consists either in facet joint steroid injection performed with radiologic guidance or in surgical excision. [Copyright &y& Elsevier]

Introduction: Greater transit use is associated with higher levels of physical activity, which is associated with lower health risks and better health outcomes. However, there is scant evidence about whether health care costs differ based on level of transit ridership., Methods: A sample (n=947) of members of Kaiser Permanente in the Portland, Oregon area were surveyed in 2015 about their typical use of various modes of travel including transit. Electronic medical record-derived health care costs were obtained among these members for the prior three years. Analysis examined proportional costs between High transit users (3+ days/week), Low transit users (1-2 days/week), and Non-users adjusting for age and sex, and then individually (base models) and together for demographic and health status variables., Results: In separate base models across individual covariates, High transit users had lower total health care costs (59-69% of Non-user's costs) and medication costs (31-37% of Non-users' costs) than Non-users. Low transit users also had lower total health care (69%-76% of Non-users' costs) and medication costs (43-57% transit of Non-user's costs) than Non-users. High transit users' outpatient costs were also lower (77-82% of Non-users). In fully-adjusted models, total health care and medication costs were lower among High transit users' (67% and 39%) and Low transit users' (75% and 48%) compared to Non-users, but outpatient costs did not differ by transit use., Conclusions: Findings have implications for the potential cost benefit of encouraging and supporting more transit use, although controlled longitudinal and experimental evidence is needed to confirm findings and understand mechanisms., Competing Interests: Conflicts of interest: All authors declare no conflicts of interest

Increasing morbidity related to Clostridium difficile infection (CDI) has heightened interest in the identification of patients who would most benefit from recognition of risk and intervention. We sought to develop and validate a prognostic risk score to predict CDI risk for individual patients following an outpatient healthcare visit. We assembled a cohort of Kaiser Permanente Northwest (KPNW) patients with an index outpatient visit between 2005 and 2008, and identified CDI in the year following that visit. Applying Cox regression, we synthesized a priori predictors into a CDI risk score, which we validated among a Kaiser Permanente Colorado (KPCO) cohort. We calculated and plotted the observed 1-year CDI risk for each decile of predicted risk for both cohorts. Among 356 920 KPNW patients, 608 experienced CDI, giving a 1-year incidence of 2.2 CDIs per 1000 patients. The Cox model differentiated between patients who do and do not develop CDI: there was a C-statistic of 0.83 for KPNW. The simpler points-based risk score, derived from the Cox model, was validated successfully among 296 550 KPCO patients, with no decline in the area under the receiver operating characteristic curve: 0.785 (KPNW) vs. 0.790 (KPCO). The predicted risk for CDI agreed closely with the observed risk. Our CDI risk score utilized data collected during usual care to successfully identify patients who developed CDI, discriminating them from patients at the lowest risk for CDI. Our prognostic CDI risk score provides a decision-making tool for clinicians in the outpatient setting., (Copyright © 2014 European Society of Clinical Microbiology and Infectious Diseases.

Intra-articular osteoid osteoma is rare and difficult to diagnose. We report a 38-year-old woman who presented with an inflammatory monoarticular arthritis in the right ankle in the context of a spondylarthropathy, otherwise well-controlled by leflunomide. This monoarthritis was resistant to all types of treatment. Investigations led to the diagnosis of an intra-articular osteoid osteoma. This original observation is the first description of an osteoid osteoma developing in a patient already known to have inflammatory rheumatism. All previous reported cases were monoarthritis consecutive to the osteoid osteoma itself and interpreted as incipient inflammatory rheumatism., (Copyright 2010 Société nationale française de médecine interne (SNFMI).

Purpose: Ankylosing Spondylitis (AS) is an inflammatory rheumatism characterized by its disease course with flares leading to progressive ankylosis of the spine related to paravertebral ligamentous and discal structures ossification. AS patients suffer significantly more vertebral fractures than control groups. These fractures could affect cervical spine. They are due to either ankylosis-related flawed spine compliance or AS-induced osteoporosis., Current Knowledge and Key Points: The physiopathology of this osteoporosis is multi-factorial, but essentially linked to AS-related inflammatory phenomenons. It is marked by reduced bone density (at lumbar spine and femoral neck), increased bone turnover (with increased urinary C-telopeptide cross-linked collagen type 1), but without any significant change in phosphocalcic blood parameters. Histological features are depressed bone formation, with either maintained or increased resorption., Future Prospects: The screening of this osteoporosis is based upon investigating people at risk (progressive inflammatory AS) using dual-energy x-ray absorptiometry and biochemical markers of bone turnover. Treatment is based upon a modulation of both inflammatory phenomenons and bone remodelling using bisphosphonates and anti-TNF alpha.

Unlabelled: The role of epidural fibrosis in postoperative sciatica is unclear. Few therapeutic trials have been published. We evaluated the mechanical effects of forceful saline injections through the sacrococcygeal hiatus comparatively with glucocorticoid injections., Patients and Methods: Forty-seven patients with postdiscectomy sciatica but no evidence of compression by computed tomography or magnetic resonance imaging were included in a multicenter, randomized, controlled, parallel-group study comparing forceful injections of saline (20 ml) with or without prednisolone acetate (125 mg) to epidural prednisolone acetate (125 mg) alone. Each of the three treatments was given once a month for three consecutive months. Outcome measures were pain severity on a visual analog scale (VAS) and the scores on the Dallas algofunctional self-questionnaire on day 0, day 60, and day 120. Analysis of variance for repeated measures and Student's t test for paired series were used to evaluate the data., Results: Forty-seven patients were evaluated. The VAS score improved significantly between day 0 and day 30 in the glucocorticoid group as compared to the forceful injection group (P = 0.01). No other significant differences were found across the groups. The VAS score improved steadily in the forceful injection group, producing a nearly significant difference on day 120 as compared to baseline (P = 0.08)., Conclusion: Forceful epidural injections produced a non-significant improvement in postdiscectomy sciatica four months after surgery. Epidural glucocorticoids used alone induced short-lived pain relief.

Intracranial dural arteriovenous fistulas draining into the spinal medullary veins (ICDAVFMs) are exceedingly rare lesions. Their diagnosis is difficult and is often made late. About twenty well documented cases have been published. We report a case in a 55-year-old woman who presented with persistent interscapular pain and neurological evidence of ascending myelopathy after therapy for cervicobrachial neuralgia. ICDAVFM should be considered by rheumatologists in patients with clinical and radiological findings suggestive of spinal cord disease, particularly if these findings indicate involvement of the medulla oblongata or cervical spinal cord.

Several drugs can induce bone disorders. Steroid-induced osteoporosis is the best known of all drug-induced bone disorders. However, bone disorders have also been described in association with newer drugs (LH-RH analogs, retinoids, cyclosporine, etc.). The purpose of this revue is to familiarize radiologists with drug-induced bone disorders in order to achieve earlier diagnosis, hence, improve treatment.

Objective: To describe the clinical and laboratory features and outcome of 6 patients presenting with remitting seronegative symmetrical synovitis with pitting edema (RS3PE) revealing a solid tumor., Methods: Patients with RS3PE who presented with a solid tumor and who had been seen between January 1, 1994, and December 31, 1996, were included in a retrospective multicenter analysis. These patients fulfilled McCarty's description of RS3PE and the following criteria: (1) bilateral pitting edema of both hands, (2) sudden onset of polyarthritis, (3) age >50 years, and (4) absence of rheumatoid factor (RF)., Results: Six male patients with RS3PE are described, of mean age 74 years (range 72-78), presenting prostatic (n = 4), gastric (n = 1), and colic (n = 1) adenocarcinomas. The clini cal picture was characterized by the classical form of RS3PE syndrome and by a deterioration in general condition, sometimes with fever. All patients were negative for RF and antinuclear antibodies. In 2 cases of prostatic adenocarcinoma serum levels of interleukin 6 (IL-6) were high, but decreased with treatment. In these 6 patients, the articular manifestations regressed totally or partially in response to corticosteroids, sometimes at low doses, associated in most cases with specific antitumoral therapy. None displayed erosion or distal bone destruction. The mean survival following discovery of RS3PE was 11 months (range 6-18), 5 patients dying of metastatic dissemination of their cancer and the 6th of myocardial infarction., Conclusion: RS3PE is a heterogeneous syndrome that can reveal a solid tumor, notably an adenocarcinoma. There exist no specific criteria to define its forms, but this syndrome should be kept in mind in the face of a deterioration in general health. Although the pathogenic mechanism is unknown, this could involve a type of paraneoplastic polyarthritis linked to the synthesis of a factor such as IL-6.

Hemophagocytic syndrome is an exceptional cause of pancytopenia. Its etiologies are most commonly viral or bacterial infections, lymphoproliferative syndromes, acquired or congenital immunodeficiencies, systemic diseases, or immunomodulatory treatment. We describe a patient with rheumatoid arthritis (RA) treated with methotrexate (MTX), sulfasalazine, and low dose corticosteroids, whose case was seriously complicated by the occurrence of acute febrile pancytopenia. The pancytopenia appeared secondary to hemophagocytic syndrome triggered by Escherichia coli septicemia. The evolution was marked by severe aggravation of RA, probably due to release of cytokines from macrophages (tumor necrosis factor-alpha, interleukin 6). Reintroduction of MTX (without sulfasalazine) resulted in partial remission and there was no reappearance of new hematological anomalies after 16 month followup. A knowledge of this syndrome is particularly important, since it mimics drug toxicity and other complications such as lymphoproliferative diseases.

Aseptic osteonecrosis is a rare extraintestinal manifestation in patients with inflammatory bowel disease; its true prevalence is not precisely known. Steroid treatment undoubtedly participates in the pathophysiology of avascular osteonecrosis, however, other factors like hypercoagulability may be involved. Two cases of bilateral osteonecrosis of the knees--the first occurring during the course of ulcerative colitis, the second in a patient presenting with Crohn's disease--are described. Specific location of the lesions and regression of symptoms, as well as the importance of magnetic resonance imaging for early recognition of osteonecrosis, are noteworthy.

This multicenter randomized, double-blind, controlled study was performed to compare the efficacy and tolerability of chondroitin sulfate (CS, Condrosulf, IBSA, Lugano, CH) 1200 mg/day oral gel vs CS 3 x 400 mg/day capsules vs placebo, in patients with mono or bilateral knee osteoarthritis (Kellgren and Lawrence radiographic score grade I to III). A total of 127 patients, 40 of whom were treated with CS 1200 mg/day, 43 with CS 3 x 400 mg/day and 44 with placebo, were included in the statistical analysis of this 3-month treatment study. In the CS groups, Lequesne's Index and spontaneous joint pain (VAS) showed a significant reduction of clinical symptoms (P < 0.01 for both parameters), while only a slight reduction was observed in the placebo group (P = ns for Lequesne's Index and P < 0.05 for VAS). The physician's and patient's overall efficacy assessments were significantly in favour of the CS groups (P < 0.01). The treatment carried out with the three formulations was very well tolerated. In conclusion, these results indicate that CS favours the improvement of the subjective symptoms, improving the joint mobility. An additional consideration is that the efficacy of 1200 mg CS as a single daily dose does not differ from that of 3 x 400 mg daily doses of CS for all the clinical parameters taken into consideration.

Objective: To compare the detection rates of chromosomal flagellin gene from Borrelia burgdorferi in synovial tissue (ST) and synovial fluid (SF) using polymerase chain reaction (PCR) techniques., Methods: B burgdorferi DNA was sought in SF and ST from 12 consecutive patients with Lyme arthritis and from 29 patients with noninfectious diseases (controls)., Results: No DNA amplification was observed in samples obtained from the 29 control patients, whereas B burgdorferi DNA was detected in all ST and/or SF samples from the 12 patients with Lyme arthritis. Results from 1 ST sample were not interpretable because of PCR inhibitors. Among the 11 remaining patients, 10 had positive ST samples, whereas only 4 had positive SF samples (P < 0.05)., Conclusion: These data suggest that detection of chromosomal B burgdorferi DNA may be more efficient in ST than SF.

Synthetic antimalarial agents can cause exacerbation of latent or patent psoriatic skin lesions. A case of psoriatic onychoperiostitis precipitated by hydroxychloroquine therapy is reported. The patient had primary Sjögren's syndrome, raising questions about the incidence and causation of the ungual abnormalities associated with this condition.

Stress fractures are exceptional in patients with reflex sympathetic dystrophy syndrome, even when bone loss is severe. We report a case of stress fracture of the navicular bone documented by magnetic resonance imaging. Recurrence of localized pain in patients with reflex sympathetic dystrophy syndrome suggests either a relapse of the syndrome or a bony fissure. Magnetic resonance imaging can provide early differentiation of these two conditions.
